Supercharging is more than likely not a good idea unless they drop the compression ratio down from 12.5:1. Then again, maybe that car has an over built top end, bottom end, internals, and an over-speced. fuel pump with plenty of over-head to handle the greater fuel requirements. Then again, again.... that all sounds like the recipe for a heavy car, an expensive car, or a heavy and expensive car... neither of which define the BRZ. Besides, Subaru already makes plenty of forced induction cars.
The goal of the BRZ is to be as organic as possible in terms of driver feel. For that, one would need a lightweight chassis and power-train, which provides linear and accessible power delivery. All requirements considered (cost, performance, manufacturability, serviceability, efficiency, packaging, weight, etc), that pretty much leaves you with a high revving naturally aspirated engine motivating a fairly light chassis riding on a good to fantastic suspension... cost dependent, of course. Without easing up on one of the above constraints (again unless it's cost), it is tough to beat the basic formula that the BRZ is built on. Case in point; though they seem different, the Porsche GT3, Ford BOSS 302, Mazda Miata, even the Integra Type R, and our very own BRZ really are fruit off the same tree.
